Excerpt from Thermal Gradient Effects on Thirteen Flush Mounted Pressure Transducers<br/><br/>Thirteen different flush mounted pressure transducers of seven manufacturers Were tested by creating a thermal gradient in them and recording the resultant zero shifts. Photographs of typical outputs are shown and the results are compared. A typical recording shows these general characteristics; 1. A very rapid change in output reaching a peak in a second or less, 2. A more gradual shift which reaches a peak in a time which may be a few seconds or more than a minute, and 3. A shift in reading which remains as long as the gradient is maintained. Examples were found in Which each of these were positive or negative. -the magnitude in a few cases was small, in many was a large fraction of its range, and in one case well in excess of the full scale range.
